Title:    “In the Eye of the Storm: Hurricanes, Climate Migration, and Climate Attitudes.”

Author: Sabrina B. Arias and Christopher W. Blair

Data users will need to unzip all folders upon download. Name the master folder "APSR Replication". Also please be sure to change the file path with your username in each code file so that the code runs on your device. If you place the unzipped replication folder on your desktop, you can change the file path in each code file by performing a find-and-replace, substituting “cb2257" for "your username".


Once these steps are completed, you need to run four files to reproduce the full results:

1. First, run "Hurricanes Full Analysis.do" in Stata - this will run all main analyses.
2. When that is completed, run "Hurricane Map.R" in RStudio - this will create the maps.
3. When that is completed, run "Equivalence Test.R" in RStudio - this will run the equivalence analyses.
4. When that is completed, run "Climate Sensitivity.R" in RStudio - this will run sensitivity analyses.


List of Supplementary Results and Information:

• Ethics Approval.pdf -- notice of IRB approval
• Ethics Submission.pdf -- initial submissions to IRB for approval
• Additional Supplementary Materials.pdf -- additional supplementary results referenced in the manuscript, along with the full text of the survey instrument
• Full Tabular Results.pdf -- full tabular results from every table in the manuscript and appendix


List of Data Files:

Survey
• florida_ballot.dta -- data on Florida ballot measures
• followup_completes_geocoded.csv -- raw data from follow-up survey
• followup_final.dta -- cleaned data from follow-up survey
• map_descriptives.dta -- data for county maps
• survey_completes_geocoded.csv -- raw data from main survey
• survey_final.dta -- cleaned data from main survey

Covariates
• countypres_2000-2020.csv -- data on county Presidential voting
• florida_ballots.xlsx -- data on Florida 2022 election
• ian_assistance.dta -- data on FEMA assistance after Hurricane Ian
• pop2021.csv -- data on county population and migration rates

Hurricane
• ian_geo.dta -- data on Hurricane Ian exposure
• ida_geo.dta -- data on Hurricane Ida exposure
• nicole_geo.dta -- data on Hurricane Ida exposure
• ian_waze.csv -- data on Hurricane Ian evacuation


List of Main Analysis Code Files:

• Hurricanes Full Analysis.do - build, clean, and analyze main data
• Hurricane Map.R - produce maps for main text and appendix
• Equivalence Test.R - run equivalence tests
• Climate Sensitivity.R - run sensitivity analyses


List of Supplemental Code Files (called by Hurricanes Full Analysis.do):

• Hurricanes Clean and Process.do - build and clean data
• Hurricane Main.do - analyze main survey data
• Hurricane Robustness.do - analyze additional survey data
• Hurricane Heterogeneity.do - analyze heterogeneous effects
• Hurricane Follow Up.do - analyze follow-up survey data


List of Other Files:

• Figures-Placeholder.txt - a blank text file contained within the figures folder. This file is a placeholder in the replication zip files. Running the analyses will fill the figures folder with figures from the manuscript

• Tables-Placeholder.txt - a blank text file contained within the tables folder. This file is a placeholder in the replication zip files. Running the analyses will fill the tables folder with tabular results from the manuscript

• READ_ME.txt - a file with instructions for replication
